Good morning!

Here are some ripple marked strata in the Silurian-aged Rose Hill Formation from West Virginia:

Tilting of these strata occurred long after the Silurian – during the late Paleozoic Alleghanian Orogeny — an application of the principle of relative dating known as “Original Horizontality.”

There are also trace fossils to be seen on these bedding planes.

This was another site that I was introduced to in April, on the GMU sedimentology and stratigraphy field trip led by Rick Diecchio.
